Hi,

I have a grid with grouping and pagination (grouping collapsed by default)
and another page for user to click to come to this page.

when user click, I will pass the ID to the grid page.
The ID is the DataKeyValue of the Grid.

1. Based on the ID, how can I expand the specific row based on the ID passed to here?
2. And if the row is in another page, how can I switch the grid's page to that page after expand the row?

Thanks.

Hi HSLaw,

Basically, there is no option to achieve this functionality out-of-the-box. You can use custom code to achieve the desired functionality. For example, you can get a reference to a particular group header item:

http://www.telerik.com/help/aspnet-ajax/grdcustomizegridgroupheaderitem.html

and according to the text, set its expanded state to true. Additionally, you can move the logic in the PreRender event handler, and get a reference to all the gridGroupHeader items on the current page, to check the text, and determine the expanded state accordingly.
I hope this information helps.
